Any "standard" MK 5 isn't likely to have comfort spacing. If that's important to you, you're going to have to find one that someone else custom ordered or order one yourself. Either that, or find a Europa or Rogue that was ordered with the Balance K body and accept the different electronics.

For what it's worth, beavers MK5 Balance Ks are all ordered with Comfort spacing. However, none of the 5s on his website are left; they're just pictured to help the ordering process. From my recent dealings with him, he has a 5a quilt maple coming in in a couple of months and a coco bolo that's due to be shipped to me sometime this week;-)
